Berberis hancockiana is a species of flowering plant in the family Berberidaceae, first described in 1917. It is endemic to Yunnan Province in southwestern China.
Berberis hancockiana was initially scientifically described and named by Tsun Shen Ying as Mahonia hancockiana. A paper was published by Joseph Edward Laferrière in 1997 summarizing the arguments for Mahonia being more properly classified as a synonym of Berberis included Berberis hancockiana. As of 2023 this is the most common classification by botanists.
